Document Summary
Animal associates a specific voluntary behavior with the consequence of that behavior. Reinforcement = increased probability of same response. Consider the following: the order of stimulation. Should the stimulus precede to follow the behavior: the timing of the stimulation. How impt. is timing b/w the behavior and the stimulus. Animal will press the lever more often to obtain the reward. Animal will press the lever less often to avoid the punishment: 2. Punishing" stimulus= poke on pneumostome when animal tries to open it. Cells underlying behavior have been individually identified. Aerial respiration = pneumostome opening: number of openings and pokes decreases in each additional session, animals remember this change in behavior for at least 24 hrs, 1. Make sure there aren"t any other factors: 2. Experimental controls: poked animals: same number of pokes", poke" applied to the closed pneumostome. What is ^: the active metabolite of vitamin a, vit. For vision, nervous system development, and normal immune response: vit.
